Specification of Letters Patent.

Patented Sept. 2, 1919.

To all whom it may concern:

Be it known that we, GOTTHILF H. ScHWARz, a citizen of the United States, residing at #125 Enfield street, Brooklyn, in the county of Kings andState of New York, and MAX VINTSCHGER, a citizen of the United States, residing at Ridgewood, in the county of Bergen, New Jersey, have invented certain new and useful Improvements in Containers, &c., of which the following is a specification.

The objects of our invention are to provide a container of can, barrel or drum form, the head-portion Of which while easily and quickly removable, when in position and locked therein, will close such container, etc., air-tight with an annular chime-joint; through a locking mechanism contained within the top central dished cover-portion; all of such mechanism being of exceedingly cheap and simple form of construction and operation; and such parts as have a tendency to wear, or deterioration, through age or much operation, are all quickly and easily renewable at a minimum cost. While not limited to such use our container herein shown, described and claimed is more especially designed and adapted for use as .a container for dry powdered materials of any and all characters, which it is necessary to protect from contact with the free atmosphere, water, and, atmospheric humidity; but in its practical application our invention is more particularly designed for use in forming metallic barrels or drums of the usual commercial sizes and forms.

Our said invention is shown, described and claimed, in the following speclfication, of which the accompanying drawing forms a part, wherein similar letters or numerals of reference designate like or equivalent parts throughout the several views; and in which- Figure 1 is a side-view in central vertical section of the top portion of one of our improved containers, of the cylindrical barrel or drum form showing our improved removable air and. moisture-proof top in the fully closed and locked position therein;

Fig. 2 is a top-plan view of Fi 1, showing the locking and sealing mec anism 1n the fully closed and locked position.

Fig. 3 is a side view in the same vertical central section as Fig. 1, showing the looking mechanism in the top-unlocking and releasing position; and

Fig. 4 is a top-plan view similar to Fig. 2, showing the locking mechanism in the unlocked and releasing position, shown in Fig. 3.

. Fig. 5 is a view in detail on an enlarged scale, of a slde-portion of Fig. 1, showing 1n full-lines the cover in the closed and locked-position, and in dotted lines the same in the unlocked and partially released posit1on, ready to be lifted up and out of the container, etc., so as to fully uncover the same, and so as to give access thereto over the full top surface area, for purposes of inspection, removal, etc., of the contents.

Referring to the drawing In the particular embodiment of our invention herein disclosed, (to which however we do not intend to limit ourselves) the reference letter A, designates the main or body portion of the container, shell usually of sheet steel in the form of a hollow cylinder, spun, struck-up or formed into shape by any suitable process and apparatus; and closed at the bottom (not shown) in any desired manner; but this closing of the bottom not being part of our invention, we have not deemed it essential to show the same herein.

As shown inthe drawing the cylindrical sheet-steel body portion A of the receptable, is provided at the top with an annular inwardly ohamfered or channeled securing chime-ring B which answers in its shape and functions to the ordinary interiorly annu larly channeled or chamfered end chimering portion of an ordinary barrel of wood.

This securin annularly channeled chimering B, is usua ly of steel, cast, rolled or bent up into proper form, usually of that shown; and is secured to the upper open end of the main cylindrical body portion of the receptacle at its lower edge in any suitable manner, which will make the annular joint between such body portion A, and chime-ring B, an air tight joint 11. One of the ways in which such joint may be made so, as shown in detail'in Fig. 5, is by slipping the chimering B down over the upper end of the cylindrical casing body-portion A, and then swaging the upper annular end portion backward into the annular outwardly flaring central channel of such chime-ring, in the form of a flattened-coil 13, so as to contact at the lower outer edge of the coil with the downwardly flaring inner-face 12 of the lower part of said chime ring at the base of the coil 13; and the joint between the extreme edge of the ring B, indicated by 14) is further madeair and mo sture proof tight by extremely tight outward forcing of the annular wall of the casing against such edge, and also if necessary the parts are further locked in place by the swaging outward underneath the outer inclined wall edge 14:, of an annular-bead 15 formed in the receptaclewall, Iwhereby upward or downward slipping movement of the chime-ring B on the receptacle is absolutely prevented; and such joint may be further made tight by soldering, electric welding, or in any other suitable and desired manner.

The annular top of the backwardly outwardlyperipherally turned securing-coil 13, forms an annular gasket-seat'13, contacting with'the annular resilient gasket-ling C of the cover C, when the two are forced together, as shown in Fig. 5 of the drawing to form an air and moisture-proof joint.

The cover C is also usually struck up,

drawn, orformed in any other desired manner, of any suitable sheet material, usually.

sheet steel; and comprises asubstantially flat circular interior bottom central portion 20; provided with an upwardly extending peripheral annular wall portion 21, which is outwardly and downwardly peripherally curved at thetopinto the open bottom a nnul-ar gasket-ring retaining-coil 22; being just sufiicien-tly inwardly curved at its lower outer peripheral edge 22, vto retain therein against accidental outwardly downward displacement, the gasket-ring C, usually and preferably formed of pure and resilient elastic Para-rubber or other like highly resilient elastic soft, compressible material, which will 'notbe deteriorated by contact with the contents of the receptacle or container, of whatever chemical composition.

The gasket-ring G is an endlessring and usually of the cylindrical form in cross section clearly shown in Fig. 5, but when the gasket-ring retaining-coil 22, is 10f other form than semi-circular such gasket .is made to conform to the shape thereof; but in any event the construction is such that such gasket ring C although firmly held in position in the retaining coil against accidental displacement by thecombined resiliency of both gasket-ring and gasket retaining-coil Y may be removed and anew one inserted in place thereof easily and quickly.

Carried and supported by the cover C,

above the gasket-ring retaining-coil 22, and with its bottom inclined face resting on the annular top of such gasket retaining coil, is the annular expansible cover locking ring D formed of any suitable material, usually of resilient 5 ring steel, and in cross-section of the su stantlally wedge shaped form shown in Figs. 1, 3 and 5, with thepoint of -the wedge peripherally directed outward.

'As shown. in Figs. 2 and 4 such cover locking-ring D is provided with'the vertical sp it-joint or out 2 5 on one-side thereof to permlt of the perlpheral expansion or contraction of such" ring; and the same is provided on one side of such split-joint 25 witha guiding-tail or lap-tongue 26 inte-;

riorly closing such slit or split-joint whether the same be open or closed, and

which, through engagement with the interior the inner annular channel of the chimering B, and such lap-tongue 26 is provided at its base with an .interiorly extending throw-lug 27; while the oppositeand opposing endof the locking-ring D is providedbeyond the split-joint 25 with a like interiorly extending throw-l 28.

Pivot/ed at its inner en by a pivot-bolt 30 to the throw-lug 27 .is the manually opcrated horizontally swinging lock-leverL,

to which is pivoted just inwardly of the adjacent pivot bolt byway of the inwardly ofiset curvedrear-portion 32, of. such locklever L, by means of the pivot bolt 33, thelock-lever connecting rod '34:, pivoted at its other end by the pivot-bolt 35, to the throw- And it will be seen by this particular construction of such-compound-lever lockingmechanism (as clearly shown inFigs. 2 and 4) when the hand-lever L is thrown to the outward peripheral and ring locking position, .(Fig. 2) the pivot bolt 33 being then thrown peripherally outward'beyond the line aar. of Fig. 2, passing throughthe center of the pivot bolts 30 and. 35, that the entire locking mechanism will when in such position, be automatically locked against any accidental displacement; and practically cannot be forced-to the open and'unlocked p'o-' Fig. 4, save purposely and sition shown in by hand. As shown in Fig. 5, the expansible curing face 35 at its rear and inner edge,

"1-15 ing-ring D is provided with the top, flat seingupper securing-lugs 36,01 the securing brackets F, (usually three innumber as shown'in Figs. 2 and 4) secured tothe bottom of the cover C by rivets 38.

The play of the 'ring I) up nd d b neath the brackets F is somewhat loo so;

that the expanding and contracting movement thereof, in looking and unlocking isnot interfered with g and when thrown out: ward to locking position '(as' shown in full-j lines. of Fig.1 7 p clined perip eral locking-face 40, coming in 5) the upperdownwardly in-L sliding contact with the coacting upper inwardly and upwardly inclined slide-face 40' of the inner annular channel or chamfer of the chime-ring B, will cause the lock-ring D to bodily descend in such manner that the lower inclined face 41 thereof, as it moves diametrically outward, will press the gasketring retaining-coil 22- bodily downward from the position shown in dotted to that shown in full lines in Fig. 5; thus bodily vertically forcing down the cover C so as to form an air-tight joint between the resilient gasket-ring C and the annular topcoil 13 of the receptacle body A, at all points. The brackets F, by contact with the inner edge of the locking-ring D also act as guides to prevent undue contraction of the locking-ring D, and departure from its circular form.

In order to facilitate the lifting ofl of the cover (I, when in the unlocked position shown in Figs. 3 and 4, a suitable handle H secured within the dished central portion of the cover is usually provided; and all the locking mechanism is contained within the dished portion of the cover; and when in the locked-position there is no projection of any of the mechanism beyond the outer edge of the outer securing channeled chime-ring B; which thus protectingly guards the same against accidental displacement during shipment, storage and handling.
